DTC Description

WARNING: This page is about a different car, the 2021 Kia Seltos. However, it is still accessible from the selected car via links, so may be relevant.

The downstream heated oxygen sensor (HO2S) is forced rich and lean and monitored by the ECM/PCM. This DTC sets when the ECM/PCM does not detect the output of the HO2S in a calibrated amount of time.
